SQLite는

public Cursor getFRUIT_LEVEL_STEP_2() 
{ 
    Cursor step_2 = sqLiteDatabase.rawQuery("SELECT count(*) FROM FRUIT WHERE " + KEY_RESULT + "='Pass' AND " + KEY_LEVEL_STEP_OK + "=1 " + "ORDER BY " + KEY_ID + " DESC LIMIT 1", null); 
    return step_2; 
} 

활동

step_2 = mySQLiteAdapter.getFRUIT_LEVEL_STEP_2(); 
step_2.moveToFirst(); 
    int count2 = step_2.getInt(0); 
    int score2 = step_2.getInt(5); 
    if(count2 != 0) 
    { 
     if(score2 == 50) 
     { 
      btn_l2.setBackgroundResource(R.drawable.star_1); 
     } 
     if(score2 == 75) 
     { 
      btn_l2.setBackgroundResource(R.drawable.star_2); 
     } 
     if(score2 == 100) 
     { 
      btn_l2.setBackgroundResource(R.drawable.star_3); 
     } 
     l2.setText("2"); 
     l2.setBackgroundResource(R.drawable.key_normal); 
     l2.setOnClickListener(new OnClickListener()

    } 

Answer 1

SELECT COUNT(*)는 하나의 열을 반환합니다. step_2.getInt(5)으로 액세스하려고하는 열 색인이 없습니다.

해결책을 제안하는 데 충분한 정보가 없습니다. 나는 단지 예외를 설명 할 수있다.
